Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an electric water purification pot, and particularly to a water purification filter for the electric water purification pot.

[0002]

[Prior art]

 An electric water purifier equipped with a water filter inside the inner container of the electric pot at a position higher than the full water level so that the water in the inner container pumped up by an electric pump can be dripped from above the water filter. Known from the past.

A water purification filter used in a pot such as the one described above contains a cleaning agent inside a case having openings on the upper and lower surfaces, and a mesh made of metal or the like is placed in each opening to remove the cleaning agent. It is designed to allow water to pass through while preventing leakage.

[0004]

[Problems to be solved by the device]

 In the electric water purifying pot using the water purifying filter as described above, if hot water comes into contact with the purifying agent during use, bubbles will be generated from the purifying agent, so a means for releasing the bubbles is required. If this means is insufficient, air bubbles accumulate inside the case, and the air bubbles prevent the hot water from coming into contact with the purifying agent, which causes a problem that the water purifying ability cannot be exhibited. For this reason, conventionally, as the metal net stretched over the opening, a metal mesh having a size that allows the bubbles to easily escape is used, and the bubbles are allowed to escape to the outside from the mesh.

However, when the mesh of the metal mesh becomes larger than a certain level, the particle size of the purifying agent must be large enough not to slip out of the mesh, and therefore, the type of the purifying agent is limited, There was a problem of high cost. Moreover, since such a metal net is an expensive part, it has been one of the factors that increase the cost of the entire product.

Therefore, in this invention, by devising the structure of the water purification filter, the size of the particle diameter of the cleaning agent is not limited, and the bubbles generated from the cleaning agent can be reliably discharged to the outside. It is an object of the present invention to provide an electric water purifying pot that has been designed as described above.

[0007]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention provides a water purification filter at a position higher than the full water level of the inner container, so that the water in the inner container pumped up by an electric pump is dropped from the upper part of the above water purification filter. In the electric water purifier described above, the water purifying filter case is provided with a vent hole for bubbles generated from the purifying agent.

[0008]

[Action]

 When the purifying agent comes into contact with the hot water, bubbles generated from the purifying agent escape to the outside through the escape hole of the case, so that the contact between the hot water and the purifying agent is not hindered. The opening of the case of the purified water filter is closed by a closing means having water permeability necessary for passing hot water, for example, a water-permeable closing sheet such as a nonwoven fabric.

【Example】

 As shown in FIG. 1, the electric water purifying pot of the embodiment is composed of an inner container 1, an outer container 2 and a lid 3, and a water purifying filter 4 is provided inside the lid 3. An electric pump 5 is provided in the lower part of the inner container 1, and the electric pump 5 leads to a discharge port 8 or a water purifying filter 4 via a pumping pipe 6 and a switching device 7.

As shown in FIG. 2, the water purification filter 4 is detachably housed in a housing part 10 provided in the central portion of the middle plate 9 of the lid 3. A water passage pipe 11 is provided on the upper surface of the storage portion 10 and communicates with the switching device 7 via the water passage pipe 11.

As shown in FIGS. 3 and 4, the water purification filter 4 includes a case body 12, a case lid 13, a purifying agent 14 housed inside, and upper and lower water-permeable blocking sheets 15 and 16 made of non-woven fabric. . The case body 12 has a large number of openings 19 defined by ribs 18 which are radially projected from the flat plate portion 17 at the center of the bottom surface, and the outer peripheral surface of the case body 12 is provided with two openings for screw-fitting with the storage portion 10. Externally threaded ribs 20, 20 'are partially provided. Engagement holes 21 and 21 'that engage with the case lid 13 are provided on the upper portions of the male screw ribs 20 and 20'.

A plurality of air bubble escape holes 2 are provided between one of the engaging holes 21, that is, the engaging hole 21 on the discharge port 8 side when the water purifying filter 4 is accommodated in the accommodating portion 10 and the male screw rib 20 below the engaging hole 21. 2 is provided. This bubble escape hole 22 is provided on the discharge port 8 side because the bubble escape hole 22 is not closed even if the water purifying filter 4 is tilted and the cleaning agent 14 is moved by opening the lid 3. Is. As a result, it is possible to prevent clogging of the bubble escape hole 22 and reduce the possibility of being caught in the bubble escape hole 22 even if the particle size of the cleaning agent 14 is sufficiently large. A water-permeable block sheet 15 is attached on the opening 19 and the cleaning agent 14 is stored thereon.

The case lid 13 is designed to drop into the inside of the case main body 12, has a flat plate portion 23 in the center, and is divided into a large number of ribs 24 radially extending from the flat plate portion 23. Of the case body 12 is provided with two protrusions 26, 26 'which engage with the engaging holes 21, 21' of the case body 12 on the peripheral wall. The case lid 13 is integrated with the case body 12 by engaging with the engagement holes 21 and 21 '. Further, a water-permeable closing sheet 16 is attached to the upper surface of the opening 25 of the case lid 13.

A cover plate 28 made of a metal plate is attached to the lower surface of the case body 12 with screws 27. This reduces the influence of heat on the water purification filter 4.

In addition, in FIG. 2, 29 is a lower plate of the lid 3, 30 is a steam passage, 31 is a hinge, and 32 is a hook. When the hook 32 is pulled up, the lid 3 opens around the hinge 31. To be done.

The electric water purifying pot of the embodiment is as described above, and after the start of boiling water, the electric pump 5 is actuated to move the water in the inner container 1 through the switching device 7 from the water pipe 11 to the water purifying filter. 4 drops.

The dropped water passes through the upper closing sheet 16 and the water dropped on the flat plate portion 23 is dispersed, and comes into contact with the purifying agent 14 through the opening 25 of the case lid 13 to lower the closing sheet. From the container 15 through the opening 19 of the case body 12 and the hole 33 of the cover plate 28 and falls into the container 1. When the temperature of the water rises while repeating the above process for a required time, bubbles are generated from the cleaning agent 14, and the bubbles are discharged to the outside from the bubble escape hole 22 of the case body 12.

Although the bubble escape hole 22 of the above-described embodiment is formed by forming a hole in the peripheral wall of the case body 12, the invention is not limited to this configuration, and the lateral width of the engagement hole 21 may be set to the case lid 13 for example. The width may be set larger than the lateral width of the protrusion 26, and the gap between the two may be a bubble escape hole. Further, a notch may be provided on the upper edge of the case body 12, and a bubble escape hole may be provided between the notch and the case lid 13.

[0019]

[Effect of device]

 As described above, according to this invention, the case of the water purification filter is provided with the air vent holes, so that the air bubbles generated by the contact of the cleaning agent with the hot water are discharged to the outside from the above air vent holes. Therefore, the closing sheet provided in the opening of the case only needs to have water permeability, and it is not necessary to discharge the generated air bubbles. Therefore, an inexpensive sheet such as a non-woven cloth can be used as the closing sheet. There is no limitation on the particle size of the purifying agent, and an inexpensive purifying agent can be used. Therefore, there is an effect that the cost of the product can be reduced.
